2. Description:
a. Shot cleaning system
High pressure fan is set on the top and sides of exit end in shot blasting cabinet, which can blow and clean remained dirt on work-piece surface and reduce loss and shot leaking ratio.
There are several nozzles in this system, the air blast also can clean remained dust on work-piece surface so as to reach a clean surface. Blowing dust is collected by dust removing system.
Wind force use self circle, high pressure fan sucks wind from shot blasting cabinet to avoid air blasting infusing air pressure balance and make sure subpressure state in cabinet and enough dust removing speed and prevent overflowing.
b. Dedusting System
Dedusting system is made up of dust removal pipe, air valve adjustment and filter cylinder dust removal. Dust removal pipe has three air valves, one is used to adjust the separation speed, the other two are used to adjust speed and air pressure of dust collector, in order to control dedusting to meet the national emission standard.
Filter cylinder dust removal is foldable cylinder sharp, external diameter is 325mm, height of pipe is 660mm. The dust removal area of filter cylinder is 20m2 and the bag type covers only 0.61 m2, so filter cylinder is easily installed. This equipment has following features:
Small volume, small occupation
High clean up efficiency, above 99% for submicron dust
Adopting new filter element as main part with long service lifetime
Reasonable structure, convenient maintenance, low cost
Energy saving, running resistance is 500-800PA; primary resistance is under 200PA, max. resistance is 1500PA(fixed by wind pressure)
Adopting digital pulse control, reverse blow
Put filter element vertically, single fixed, safe and convenient checking
Dust barrel, dust cart and helix discharge device are optional
